Question

proved some blance for

simple displacement reaction​

Answer 1

Answer:

Usually, when two compounds react, both cations or both anions will change partners, producing a double-displacement reaction. You can predict whether a single-displacement reaction will occur by comparing the reactivity of an element using an activity series table.

Answer 2

Answer:

The general pattern of a single replacement reaction is shown below.  This includes groups 1 and 2, some of group 13 and 14 elements, and the transition metals.  We are not quite done though since our reaction is not currently balanced.
